Abstract

The invention discloses a cyclic hoisting tool and relates to the field of hoisting. The cyclic hoisting tool comprises a supporting part and a hoisting part. The supporting part comprises a base (1) and a first main rod (2) fixed on the base (1), wherein the base (1) consists of two steel plates provided with adjustable bolts (3); the hoisting part comprises a second main rod (4) and a cantilever (5); the second main rod (4) and the first main rod (2) are sleeved for connecting the two parts; the cantilever (5) is circular and is provided with a guide rail; an electric hoist (6) and an electric hoist (7) which are opposite to each other are arranged on the guide rail and can slide on the cantilever (5); steel balls (8) are arranged at a gap between the electric hoist (6) and the electric hoist (7) on the guide rail. The hoisting tool has the advantages that the service range is wide; and the occupied space of the base is small, the operation radius is small, the power outage range is narrowed, and the working efficiency is greatly improved, thereby shortening the power outage cycle.

Description

technical field [0001] The invention relates to the field of hoisting, in particular to a circulating hoisting tool. Background technique [0002] As the service life increases, substations often face renovation and renewal, and the renovation of substations requires replacement of old outdoor equipment, such as voltage transformers, knife switches, arresters and other outdoor equipment, which are usually installed on the structure. However, outdoor substation equipment is bulky, heavy, and difficult to handle by manpower, so it usually needs to be hoisted by crane. Neighboring bays need all power outages, which will inevitably expand the scope of power outages, directly affect the normal power supply, and then affect people's normal life. [0003] Based on the problems identified by the analysis of the actual situation on site, we confirmed that the main reason for the large-scale power outage during the replacement of substation equipment is the use of cranes for hoisting...
